A "cropped sensor" is a digital imaging sensor smaller than the traditional film size for the system in which it is used. APS-C is a cropped-sensor format compared to traditional 35mm-film or to "full frame" digital sensors. Cropped sensor may also refer to any smaller sensor, particularly when ...

I have a most vexing problem.
I have a Nikon d5100 (roughly a year old) which up until two days ago handled exposure and metering just fine. However, at night, in a well lit room (florescent bulbs) ...

I know that the image circle of FF-lenses is bigger than it needs to be on APS-C sensors, thus the FOV spears narrower. I've heard that APS-C lenses sit closer to the sensor, thus projecting a smaller ...

I see a lot of questions comparing full frame (e.g EF for Canon, FX for Nikon) and crop lenses (e.g. EF-S for Canon, DX for Nikon) but I can't find the answer to what would be the differences between ...

I have a 600D and a 7D and I use the kit lens " EF-S "18-55mm and the 55-250 mm , and I am thinking of buying a 24-105mm f4 IS USM L... so does the EF-S suffer from the same 1.6x crop factor as the ...

I have been primarily shooting with a Canon 18-135 f/3.5-5.6 for several years now, and I am not completely satisfied with it. The problems I have are:
A bit too wide on the low end
A bit too short ...

I have a Canon EOS 550D with a APS-C sensor. I have two lenses, (1) Canon EF-S 18-135mm f/3.5-5.6 IS and the (2) Canon EF 50mm f/1.8 Mk II.
If I use the 50mm focal length in the first EF-S lens... I ...

I’ve read a lot of lens reviews that say something like, “in order to get the maximum sharpness out of this lens, you’ll need to stop it down” to f/2.2 or f/2.8. I’m shooting on an APS-C camera. Is ...

1- I know different focal lengths change the depth and flatness of an objects in the picture. For examples longer focal lengths make objects appear flatter so they will be appropriate for portraits. ...

I know that if I take my full frame lens (for example 50mm/1.4) and put it on an APS-C sensor, the field of view (FOV) changes. So what I will do is move back to retain the same subject magnification. ...

Lots of people say that full frame sensors receive more light than cropped sensors. I have never found a proof of this claim so I tried to do the computation by myself, and proved the contrary! Could ...

I am about to upgrade to a Canon 7D for my birding using my 400mm 5.6L lens. With the 1.6 crop factor sensor that gives (roughly) a magnification factor equivalent to my other option, a Canon 5D mkII ...

If I put a DX lens on a Nikon D700, it will reduce megapixels to 5.1.
I understand that FX pixels are about 2.5 times larger than DX pixels. Would I be correct to assume that, therefore, my FX image ...

There was recently a video posted about how different focal lengths affect portrait photography, specifically how distortion at smaller focal lengths have more distortion and are less flattering.
So ...

I've read several times that a 50mm lens will make features like noses noticeably stand out compared to an 85mm lens. However, I'm never sure if the post/article is describing results on a full frame ...

I'm considering switching to the Micro Four Thirds system. Finding lenses which match my style is a key part of that, and "normalizing" via crop factor is a convenient tool.
The crop factor for Four ...

I have a Singh ray 2 stop Graduated ND with soft step. I find it very difficult when I uses it with my Canon 17-40 f4L lens on my Canon T2i, which is a crop sensory body.
Since it is soft step, I am ...

I know EF-S lenses are "optimized" for crop sensors but what are the exact advantages to using an EF-S lens? Does it give better color, sharpness, depth of field, etc...?
In addition, do EF-S lenses ...

Shooting: for portraits, landscapes, candids etc.
Can get a 4500 acuations 5dmarkI for $800 and its clean OR get the refurbed 60d w/ Loyalty program. I am unconcerned w/ video aspects of 60d. Is a 5 ...

I have a Canon 550D which I've been using for around a year now. I really love it and have learned a great deal with this and the 18 - 135mm kit lens. But now with experience I feel the need to get ...

Why did camera manufacturers create crop sensor cameras? Was there a business reason? Did they figure that crop sensor cameras are cheaper to manufacturer, which would in turn lower prices and make ...

I'm not talking about changes to the focal length.
I've read many post that say in full frame camera the pixel density is lower compared to crop sensor camera's and so it captures more light and has ...

I'm trying to achieve maximum depth of field without sacrificing light. I have a micro-4/3rds camera and i want to attach a full frame lens to it for the large and constant aperture. My question is, ...

I can see the benefit of designing and manufacturing a wide-angle lens specifically for APS-C sized sensors instead of full-frame sensors: you will get smaller, lighter, and cheaper lenses.
But is it ...
